3 Claims.

One form of the invention is illustrated in the accompanying drawing, in which Figure l is an elevational view of the device as it appears on the typewriter. The whole arrangement is held and adjustedbackward or forward as illustrated in Figure 1 where it is a bushed loop for fastening to the back of the machine 4 and I5 loops over the back cross rod 5a, the screw action adjusts the card holder 1 up or down. The card holder 1 is held by the cross rod-6 and may be raised or lowered from the platen roll and actuated by the arms I21) and l3b' and the helical extension springs, I20, I211 and I30, 130?, as illustrated in Figs. 2 and 3. The small holes in 1 are for adjusting the card for close writing. The Y arms 12b and l3b have extension tubes for carand 12 represent the adjusted holding plates. 1

Figures '2 and 3 show the holding plates, where Figure 2 is for the platen roll end shafts and Figure 3 direct on the full perimeter of I the platen roll, in which both Figures 2 and 3 have the same action. Both may be presseddown for adjustment, or better in combination with the lever l2a and l3awhere l2a: and I33: pries the plates l2 and I3 apart on the swivel pin 5 and 5a, better illustrated in Figure Land drawn together by the spiral spring I20, the most flexible of springs and thus creating a positive effect. Theswivel pins 5 and 5a are the extension of the cross holding rods Sand 5a.

Figure 6 represents the card holder where l is the plate on which 5 is set and through which the rod 6 passes and on which the card holder revolves, this in turn is actuated by the arms I22) and I31) as shown inFigures-2 and 3. Just before the rollers 8 the plate 1 has a slight offset which throws the card or paper directly under .I claim: I v

1. In a. card-holding attachment for writing machines provided with a carriage and a platen mounted therein,a pair of detachable, hinged clamping plates attachable at. each end of the 5 platen; springs for holding each pair of clamping plates in operative position with respect to the platen; cross-rods for holding said clamping plates in spaced relation axially of the platen; a spring-pressed bail member mounted on 10 the clamping plates; a paper pressing plate, having multiple rollers thereon and observation holes therein, slidably mounted on said bail member and designed to press against the platen to hold a card to-be written upon; and adjustable rod-members removably mounted for connecting one of the cross-rods and the platencarriage to retain the device in its card-holding position. i

. 2. A card-holding attachment for writing machines having a carriage and a platen; said attachment comprising,-'a pair of detachable clamping plates, operative with jaws, fixed at either end of the platen; a lever operatively installed between each pair of said plates and 5 adapted to open the jaws thereof; parallel crossvrods designed to hold said plates parallel with other and spaced relatively to said plates; helical extension springs on each pair of said plates, designed to hold the jaws thereof .in their 'service position; a spring-pressed swinging arm vmounted on a pintle hinge on the inner side of each pair of clamping plates; a cylindrical socket rigidly installed in the inner lower position of against the platen to hold a card thereto to be 40 written upon; and adjustable means for removably connecting one of said cross-rods with the carriage of the platen for holding said attachment in its operating position on the writing machine.

' 3. In a card-holding attachment, of the character described, for writing machines provided with a carriage and a'platen mounted therein,

a pair of hinged installationplates consisting of operative jaws detachably set on and about the platen at each end thereof and designed to hold said attachment in a service alignment with respect to said platen; rigid means for holding said installation-plates parallel with each other and spaced in longitudinal relation to the platen;

hinged means for conveniently opening the jaws of said installation-plates for attaching said card-holding device to said writing machines and for detaching the same therefrom; extensionsprings on said jaws for automatically closing the jaws to hold said installation-plates in their service position on and about said platen; a spring-pressed bail mounted on the inner sides of said installation-plates; a paper-retaining plate slidingly installed on said bail and designed to press against said platen to hold a card securely to be written upon; observation-perforations made through said paper-retaining plate to aid an operator in adjusting his card for writing thereon; and adjustable and detachable means for connecting the card-holding attachment to the carriage of the platen.
